Is there any Dalvik bytecoder available?

 Hi:
As part of my research I implemented a runtime bytecoder for Java apps
based on Javassist. The idea is to introduce code to execute code
remotely based on current context. Since the context is not the same
at every moment, I need to perform the bytecoding at every execution
(if needed).
I tried to port my code to Android in order to test it on mobile
devices (I already tested it on win mobile and iphone using phoneme
and jamvm respectively). However, I could not find any bytecoding tool
available for Dalvik.
Is there any Dalvik bytecoder available or an ongoing project that I
can join/check that is working on this issue?
If not, is there any other alternative beside running a decompiler for
dex files, and modifying it manually?

Thanks,
--Gonzalo

I'm not sure what you mean by "bytecoder".

You can generate Java bytecode and convert it with "dx", but most
Android devices are a bit resource-limited to run dx directly.

 http://code.google.com/p/smali/ is an assembler/disassembler for DEX.

1. detecting shake movement without draining the battery

Yes the only way to do it hold a wake lock.  Someone needs to keep running
to monitor the stream of data from the sensor to determine if it looks like
it is shaking.  The NDK won't help you in any way here, unless your code for
computing whether there is a shake from the data stream can run
significantly faster as native code and thus use less CPU.

The current accelerometers don't have a "detect shake" thing inside of
themselves, nor is there any facility or API for the platform to be woken up
by it and tell the application, if it did.

2. Example Populating List from Backend Database?

I've been poking around and haven't come across any good examples/
tutorials
of how to populate a list from an external data source such as a
hosted,
mySQL database. Does anyone know of any tutorials or chunks of source
code?
I think the standard Android architecture for this would involve
communicating
via http and receiving data back in XML format. Then on the backend
there
would be some sort of mySQL db with stored procedures and server
extensions
that can talk to the Android app. From the GUI a data refresh is
triggered
as you scroll down the list (and run out of populated items).

Any pointers would be truly appreciated. Thanks!
